If we could do that it would be a great help. This is my first time doing this and I'm not really sure what to do.
hi J,
Use the marked up drawing for reference.
Amp 'A' , is an inverting amplifier with a gain [ or attenuation] of -Gain = R2/R1
Amp 'B' is a non inverting amplifier, so +Gain= 1+ [R4/R3]
Amp 'C' is non inverting 'buffer' with +Gain of 1
Amp 'D' is a 'summing' amplifier.
The -Gain1 = R7/R5,,,,,,,,, -Gain2 = R7/R6
The non inverting input voltage 2V is divided by R8 and R9, so +vin =1V
So for Amp 'D' the over all gain is ???
[remember that R5 and R6 are in parallel as far as the gains for Amp 'D' are concerned]
For Amp 'C' , R10 and R11, with the 1uF form a low pass filter, ignore this for the DC analysis.
So you work out the gains of Amps A , B and C first, then post the results, then we will cover Amp 'D'
BTW the Vout you have worked out is wrong.
